3.

A statue stands on the top of a 2m tall pedestal. From a point on the ground, the angleof elevation of the top of the statue is 60% and from the same point, the angle of elevationof the top of the pedestal is 45°. Find the height of the statue.​

Answer»

Answer

  • The height of the statue will be 2(√3-1) m

Exolanation

Given

  • Length of the statue on a pedestal = 2 m
  • Angle of elevation of the top of the statue from the GROUND = 60° from the same point
  • Angle of elevation of the top of the pedestal = 45°

To Find

  • The height of the statue.

Solution

We are given with,

  1. Angle ABC = 60°
  2. Angle DBC = 45°

We know that,

DC = BC = 2 m

In TRIANGLE DBC,

➝ tan 45° = DC/BC

➝ 1 = 2/BC

➝ BC = 1 × 2 = 2 m

Let 'h' be the height of the statue.

In triangle ABC,

➝ tan 60° = AC/BC

➝ √3 = AD+DC/BC

➝ √3 = h+2/2

➝ 2√3 = h + 2

➝ h = 2√3 - 2

➝ h = 2(√3-1)

Therefore, the height of the statue is 2(√3-1)

Answer:

(i) HCF of 24 and 40 is 8.

∴ 24 : 40 = 2440= 24 ÷ 840 ÷ 8= 35 = 3 : 5

Hence, 24 : 40 in its simplest form is 3 : 5.

(ii) HCF of 13.5 and 15 is 1.5.

13.515=135150The HCF of 135 and 150 is 15.=135 ÷ 15150 ÷ 15=910

Hence, 13.5 : 15 in its simplest form is 9 : 10.

(iii) 203 : 152=40 : 45

The HCF of 40 and 45 is 5.

∴ 40 : 45 = 4045=40 ÷ 545 ÷ 5=89 = 8 : 9

Hence, 623 : 712 in its simplest form is 8 : 9

(iv) 9 : 6

The HCF of 9 and 6 is 3.

∴ 9 : 6 = 96=9 ÷ 36 ÷ 3 = 3 : 2

Hence, 16:19 in its simplest form is 3 : 2.

(v) LCM of the DENOMINATORS is 2.

4 : 5 : 92 = 8 : 10 : 9

The HCF of these 3 numbers is 1.

∴ 8 : 10 : 9 is the simplest form.

(vi) 2.5 : 6.5 : 8 = 25 : 65 : 80

The HCF of 25, 65 and 80 is 5.

∴ 25 : 65 : 80 = 256580= 25 ÷ 565 ÷ 580 ÷ 5=51316 = 5 : 13 : 16

Why the value of 'g' is greater at poles in comparison​

Answer»

Step-by-step explanation:

56. It is frequently stated that the value of the acceleration due to gravity at the pole is larger than at the EQUATOR because the poles are closer to the center of the EARTH due to the earth's oblateness. ... The measured value is larger because the earth's density is not uniform but increases TOWARD the center.

Does your deposited money grow in the bank? How?​

Answer»

Answer:

usually takes about two business DAYS for a deposited check to clear, but it can take a little longer—about five business days—for the bank to receive the funds. How long it takes a check to clear depends on the amount of the check, your relationship with the bank, and the standing of the PAYER's account.The BALANCE in your savings account earns interest because the bank USES your MONEY to fund loans to other people. In other words, the bank pays you to use your money. The interest you receive from your savings account balance usually is compounded daily.

If cos alpha/cos beta =m and cos alpha/sin beta=n,show that (m²+n²)cos² beta =n²​

Answer»

Step-by-step EXPLANATION:

GIVEN:-

  • \sf m =  \dfrac{cos \alpha}{cos \beta}  \:  \: , \:  \: n =   \dfrac{cos \alpha}{sin \beta}

To Prove:-

  • \sf (m^2 + n^2)cos^2 \beta = n^2

PROOF:-

\sf m =  \dfrac{cos \alpha}{cos \beta}  \:  \: , \:  \: n =   \dfrac{cos \alpha}{sin \beta}

\sf cos \beta =  \dfrac{cos \alpha }{m} \:  \:  ,\:  \: sin \beta =  \dfrac{cos \alpha }{n}

\sf cos^2 \beta =  \dfrac{cos ^2\alpha}{m^2} \:  \:  ,\:  \: sin^2 \beta =  \dfrac{cos ^2\alpha}{n^2}

Now, Adding Both

\sf \implies cos^2 \beta  +sin^2 \beta  =  \dfrac{cos ^2\alpha}{m^2}  +  \dfrac{cos ^2\alpha}{n^2}

\sf \implies 1  =  \dfrac{cos ^2\alpha}{m^2}  +  \dfrac{cos ^2\alpha}{n^2} \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \bigg[{sin}^{2} \theta +  {cos}^{2} \theta = 1 \bigg]

\sf \implies 1  =   \bigg(\dfrac{1}{m^2}  +  \dfrac{1}{n^2} \bigg)cos ^2\alpha

\sf \implies 1  =   \bigg(\dfrac{ {n}^{2}  +  {m}^{2} }{m^2 {n}^{2} }  \bigg) \times cos ^2\alpha

\sf \implies 1  =   \bigg(\dfrac{ {n}^{2}  +  {m}^{2}}{{n}^{2} }  \bigg) \times  \dfrac{cos ^2\alpha}{ {m}^{2} }

\sf \implies 1  =   \bigg(\dfrac{ {n}^{2}  +  {m}^{2}}{{n}^{2} }  \bigg) \times  cos ^2\beta \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:  \:   \bigg[cos^2 \beta =  \dfrac{cos ^2\alpha}{m^2}  \bigg]

\dashrightarrow\boxed{  \rm{n}^{2}   = ({n}^{2}  +  {m}^{2})cos ^2\beta}

Hence Proved

1)PRACTICAL APPLICATIONS OF SURDS IN DAY-TO-DAY LIFE.. (atleast for 4 marks) ( appropriate answer will be marked as the brainliest)​

Answer»

Answer:

SURDS Definition

Surds are the square roots (√) of numbers which cannot be simplified into a whole or rational number. It cannot be accurately represented in a fraction. In other words, a surd is a root of the whole number that has an irrational value. Consider an example, √2 ≈ 1.414213. It is more accurate if we leave it as a surd √2.

Types of Surds

The different types of surds are as follows:

Simple Surds – A surd that has only one term is called simple surd. Example: √2, √5, …

Pure Surds – Surds which are completely irrational. Example: √3

Similar Surds – The surds having the same common surds factor

Mixed Surds – Surds that are not completely irrational and can be expressed as a product of a rational number and an irrational number

Compound Surds – An expression which is the addition or subtraction of two or more surds

Binomial Surds – A surd that is made of two other surds

Six Rules of Surds

Rule 1:

a×b−−−−√=a−−√×b√

Example:

To SIMPLIFY √18

18 = 9 x 2 = 32 x 2, since 9 is the greatest perfect square factor of 18.

Therefore, √18 = √(32 x 2)

= √32 x √2

= 3 √2

Rule 2:

ab−−√=a√b√

Example:

√(12 / 121) = √12 / √121

=√(22 x 3) / 11

=√22 x √3 / 11

= 2√3 / 11

Rule 3:

ba√=ba√×a√a√=ba√a

You can rationalize the denominator by multiplying the numerator and denominator by the denominator.

Example:

Rationalise

5/√7

Multiply numerator and denominator by √7

5/√7 = (5/√7) x (√7/√7)

= 5√7/7

Rule 4:

ac√±bc√=(a±b)c√

Example:

To simplify,

5√6 + 4√6

5√6 + 4√6 = (5 + 4) √6

by the rule

= 9√6

Rule 5:

ca+bn√

Multiply top and bottom by a-b √n

This rule enables us to rationalise the denominator.

Example:

To Rationalise

32+2√=32+2√×2−2√2−2√=6−32√4−2 =6−32√2

Rule 6:

ca−bn√

This rule enables you to rationalise the denominator.

Multiply top and bottom by a + b√n

Example:

To Rationalise

32−2√=32−2√×2+2√2+2√=6+32√4−2 =6+32√2

How to Solve Surds?

You need to FOLLOW some rules to solve expressions that involve surds. One method is to rationalize the denominators, which helps to eject the surd in the denominator. Sometimes it may be mandatory to find the greatest perfect square factor to solve surds.
